The story of the discovery of the book here translated so resembles a romance as to appear like a flower in the dry and dusty field of patristic lore. A short treatise called Philosophumena , or “Philosophizings,” had long been known, four early copies of it being in existence in the Papal and other libraries of Rome, Florence and Turin. The superscriptions of these texts and a note in the margin of one of them caused the treatise to be attributed to Origen, and its Edito princeps is that published in 1701 at Leipzig by Fabricius with notes by the learned Gronovius. As will be seen later, it is by itself of no great importance to modern scholars, as it throws no new light on the history or nature of Greek philosophy, while it is mainly compiled from some of those epitomes of philosophic opinion current in the early centuries of our era, of which the works of Diogenes Laertius and Aetius are the best known.
